i suspect this might be the sign of some interrupt problems.

yeah, it should be a drop-in replacement, so what you see is a bug
either in the -rt kernel or in the upstream kernel. I'm wondering, does
rawhide kernel rpm work? It's currently at 2.6.20-1.2922.fc7 which ought
to be roughly the same vanilla base as -rt has. So if that kernel works
for you then this is a regression in the -rt kernel.
